TYPE-PEOOFING GAGE.

Specification of Letters Patent.

Application filed. October a, 1912. SerialNo. 723,790.

To all whom it may concern Be it known that I, CHAnLns J. TAYLOR, a citizen of the United States, residing at Cicero, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Type-Proofing Gages, of which the following is a specification.

This invention pertains in general to gages adapted for positioning and retaining a sheet of paper in proper register for taking impressions and has more particularreference to a gage for registering type forms or plates and adapted to be used by compositors in making proofs in colors, thus doing away with a regular printing press which has heretofore been customarily used for this purpose.

One of the objects of the present invention is the provision of a device of this character which may be used on stone, or other i1nposing surface, with a mallet or planer, or on any kind of platen or cylinder hand press and which can be readily moved about from place to place, and is not attachable in any way to the press or to the imposing surface upon which it is used.

Another object is to provide a device, complete in itself, which may be utilized in making proofs with narrow margins such as are required in proofing type forms and, which is so constructed that the top may be removed when the form is inked, thereby obviating offsetting from the gage onto the planer, tympan, or cylinder as the case may be.

Another object is to provide adevice of this character which will be simple in con struction, cheap to manufacture and easy to use, and which may be employed in connection with type forms or engraved plates and as an accessory to any preferred type of printing press, or independent of a press.

Other objects and advantages of my invention will be readily understood by those skilled in the art as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawings.

Referring to the drawings-Figure 1 is a perspective view of a proofing gage embody ing my invention; Fig. :2 is a transverse sectional view through one arm ofthe device showing the dowel connection between the top and the base; Fig. 3 is asimilar view showing the top separated from the base; Fig. 4 is a perspective view of another form of my invention; Fig. 5 is a transverse sectional view through the device showing one of the adjustable guides; and Fig. 6 is a transverse sectional view showing the dowel connection between the top and base of the gage shown in Fig. 4.

By reference to the drawings, and more particularly to Figs. 1, 2 and 3, it will be observed that the gage comprises a base formed by two arms 7 and 8 joined together at their ends and extending at substantially right angles to each other. The basehas a flat bottom adapted to be laid upon a stone or other imposing surface and the arms, which may be constructed of metal or other suitable material, are made of any desired length. Upon the upper face of the base there is disposed a detachable top or a guide 9 shaped to correspond with the contour of the base and provided adjacent its inner edge with a guiding shoulder or bead 11 against which two edges of the paper to be proofed may be positioned. A ledge 12 is formed between the inner edge of the top and the shoulder 11 upon which the edges of the paper may be laid.

The lower face of the top or guide 9 is provided at intervals with downwardly projecting dowel pins 13, another suitable devices adapted to fit into suitably shaped depressions or apertures 14; provided in the arms of the base. These dowel pins, when placed in cooperative relation with their respective apertures, serve to detachably retain the top in position on the base, a suiticient number of pins being employed to insure the requisite positioning of the top relatively to the base.

When the device is to be used it is positioned adjacent a type form or plate from which the impression is to be taken and the proofing sheet 15 is disposed over the form with two of its edges abutting against the guiding shoulder 11. The impression is then taken by means of a mallet or, if the device is used in conjunction with a press, the

cylinder or platen may be brought into cooperative relation with the ,paper to produce the impression thereon from the form. The paper is then removed. and another form is substituted for the one from which the impression hasbeen taken. The paper is then replaced and brought. into register with the new form by positioning its edges against the guide which will cause the paper to be positioned and registered for the next color Patented Oct. 28,1913.

impression. This operation may be repeated as many times as there are colors to be printed on any particular sheet. lVhen it is desired to ink the form the top 9 is lifted off from the base so that it will not become positor to register proof of blank work onruled or blank stock and to get straight proofs of book pages and the like and, also, to obtain narrow margins on proofs which is very essential in proofing type forms. The device also enables a master-printer to obtain complete proofs on any kind of stock at small expense and with considerable rapidity, so that accurate proofs in colors may be obtained by the compositor and without the use of an expensive press used by another department.

In the modified form of my invention, disclosed in Figs. 1, 5 and 6, I have provided an adjustable guide which may be regulated to produce margins of different widths, if desired. This form of my invention comprises the base 16, substantially similar in outline to the base previously described, and a top 17 detachably mounted thereon is held in position by means of dowel pins 18 fitted in suitable apertures .19, as best shown in Fig. 6. The upper face of the top, however, instead of being provided with a stationary guide or bead, is equipped with a plurality of adjustable guide members 21 projecting upwardly and adjustable in slots or apertures 22 formed in the top or guide. The guide members, as will be readily understood from an inspection of Fig. 5, each comprise a body 23 slidably mounted on arod 24 mounted longitudinally of the aperture 22 in the top 17 and provided with a downwardly projecting finger or tooth 25. The base 16 is recessed beneath the apertures 22 to accommodate a traveling nut 26 mounted on a threaded rod 27 which extends transversely of the base. This rod may be rotatably mounted in any suitable manner and, in the present instance, I have shown both ends as projecting through the side walls of the base, one end being provided with a countersunk nut 28 and the other end having a knurled knob 29 by means of which the rod may be rotated. The traveling nut 26 is provided on its upper face with a recess adapted to accommodate the down wardly projecting tooth 25 so that when the nut is moved back and forth upon rotation of the rod the guiding member 21 will be moved with it across the face of the top 17. It will be manifest that by manipulating the rods 27 the guides may be disposed in any desired position to produce a margin of the required width. In the present instance I have shown one arm of the base as provided with two of these adjustable guides, and the other provided with only one, but it will be obvious that the number employed may be varied depending upon the size of the device. In this embodiment of my invention the top is also removable to' permit inking of the form without smearing the gage and it will be observed that, when the top is lifted off from the base the guides 21 are removed with it, since the teeth simply set into the open-topped recesses formed in the upper faces of the nuts 26. hen the top is replaced the teeth 25 will again be seated in the nuts 26 and cooperatively engage therewith so that the guides may be adjusted by manipulation of the rods, as previously described.

In the embodiments of my invention above described the combined height of the base and the removable top is substantially equal to the height of the type so that when the device is employed on an imposing surface or stone it provides a rest for the planer as well as a guide for the paper, thereby contributing toward the production of accurate and perfect proofsQ It is believed that my invention and many of its attendant advantages will be understood, by those skilled in the art, from the foregoing without further description and it will be obvious that various modifications in structure may be resorted to without departure from the spirit of the invention or the sacrifice of any of the material ad vantages thereof.
